Description

ftp_async_get() retrieves remote_file
from the FTP server, and saves it to local_file
locally. The transfer mode specified must
be either FTP_ASCII or
FTP_BINARY. The difference between
ftp_get() is that this function retrieves the file
asyncronously, so you can do other things in your program while the
file is downloaded.

In the example above, "newfile" is 100
bytes smaller than "README" on the FTP
server because we started reading at offset 100. If we have
not have disabled FTP_AUTOSEEK the first
100 bytes of newfile will be '\0'.
